Congrats! Good boat.
I had a Tyee and they were mounted slightly less than half-way back along on the gunnels at the fishing deck. Just check them out so they will swivel in without trouble, leaving room to hook up the cannon ball, etc. I had the lead beds in the motor well for easy stowage without unclipping them. There's another thread here about mounting on a Wellcraft - good info. Definitely through bolt them - with back-up and bedding compound, that much better.
Canvas - where are you? Lots of good places up and down the Island. I've used H.A.M. near Duncan. Good guy, reasonable and avid fisherman. Someone else mentioned on another thread Fawcett, near Parksville I think.
Enjoy your summer on the new boat!
